The teenage Olympian demands that we ask a simple question of ourselves:
Who was I at that age?
I was young. I was immature. I flipped burgers. I walked dogs.
I couldn't have walked into a crowded arena, my country's hopes in tow, and walked out a champion.
Of course I didn't have the physical gifts, but more poignantly, I didn't have the mental faculties.
I was a freaking kid.
That's what makes the following 20 athletes so captivating, and why the sports world will have such an intent focus on their endeavors this summer in London.
These kids have already risen to the top of their respective disciplines, performing with grace and certainty on some of the grandest stages imaginable.
And here we are at the grandest of them all, a stage where they can bend the arc of what we think possible.
